Versuchsvorschrift
2-Hydroxyimino-3-oxo-5-phenyl-pent-4-enenitrile (4.0 g; 0.02 mol) is treated with methanesulfonyl chloride and triethylamine as described in example 3.4. The crude brown product is recrystallized from 40 ml of ethanol. 2-Methylsulfonyloxyimino-3-oxo-5-phenyl-pent-4-enenitrile (2.2 g; %) is obtained as a light ochre solid (mp 163-165° C.).
